-There are many kinds of encryption used in our everyday communication. Online and offline, over the internet and in person. In this article, I will explain the basics of how encryption should work in theory. I explain in [this article](/2020/01/26/rsa1.html) why encryption is important, and why *you* should care about it.

 Previously, we talked about how *symetric* encryption works. This is by having a shared key that both parties use to simultaniously encrypt, and decrypt the data. (See Ceasar Cipher for example).

 2. RSA is considered the standard for extra-seure communication.
 3. EC is a newer, faster, more transient encryption method.
